Rauf, I really should have come to your site sooner. Fantastic photos & great writing. I have to answer your past questions from Jan. 11th.
"Does the life of an artist interfere with your appreciation of his or her art music or literature?"
YES! One example, an actor I liked in a few movies and who is very good looking, he totally repulses me now and even being so great looking, matters not at all, because I think he's scum, because of his personal life. I made the mistake of several times, reading about the personal lives of famous people that I admired and almost every time, I was disapointed. I learned long ago to not look them up. I watch their movies, listen to their music, but I don't read anything about them in magazines, internet, etc., unless I happen to come across someone's blog or someone tells me about, "So and so got divorced, a sex tape, blah blah blah." I don't want to know anymore, usually.
"Is knowing more about the person you admire most, a good idea?"
90-98% of the time, no. The person I admire most would have to be Jesus Christ and He is the only person I could never be ashamed of. If I was famous and people looked my past up, they might find things they are not proud to know. Everyone has a past. Everyone makes mistakes. No one is perfect. I believe in second, third, ... chances.
Very good questions-questions I've thought about so many times.
Have a great day!
